The relation of the parts is such that before the tool84 operates to cut off a blade from the strip the pins 104 will have been pushed by arms 91 and 113 through apertures in the projecting end of the strip, Which portion of the, strip will become the blade A when out oil by the tool and will besupported by the pins 104.

After the blade has been cut oflf .the cam 109 will push the rack 108 from the bladereceiving position in Fig. 4'to the blade transferring or delivering position, (Fig. 5),

at'which position blade-assembling rods 115' are mounted in alignment or register with the pins 104, (Figs. 2, '8, 9 and 10). The rods 115 are moved toward and from the pins 104, being adapted to engage'the pins 104 to push them outwardly from the blade while the rods 115 pass through the corresponding apertures in the blade and enter the bores 105a in arm 105 to receive the "bladeupon the rods, and then the rods retreat carrying the blade with them and leaving the pins 104 pushed outwardly to be pressed forwardly by'arm 113 when arm 105 has returned to bladefreceiving position to receive another blade, and so on successively for each blade. Two rods 115 are utilized to receive a blade. The rods 115 are supported in spaced relation and secured at adjacent ends to upright 116a on'base 116 that rests on plate 117, the outer ends of the rods being provided with'key-hole-like slots 118, near opposite ends, receiving screws or studs 119 near opposite ends of plate 117, whereby the bases may be placed upon plate 117 and adjusted lengthwise to be held by the screws,

and correspondingly removed. Latches 120 are. pivoted on plate 117 adapted to be turned behind the corresponding base to.

retain the latter in cooperation with screws 11%} and to be turned to one side to release the base, (Figs. 11 and 12). Plate 117 is supported to reciprocate to move the pins 115 toward and from the blades supported on arm 105 in the blade delivery position of Figs. 5 and 8. Plate 117 is securedby screws 121 to a slide member 122 guided by bearing blocks 123 secured upon a crossshaped member 1 4, whose end portions 12400 are guided by bearing blocks 125 secured upon support or saddle 126 that is secured upon frame 1, (Figs. 2,3, 11 and 12). A pin 127 depends from member 124 through a slot 128 in support 126 and said pin is engaged by the forked end of a lever 12%) pivotally supported at 130 on framing 44, (Figs. 1 and 2). A cam 131 secured on shaft rocks the lever 129 to reciprocate the member 124 with member 122, plate 117 and rods 115 towards and from the blades Y advances with a pair of rods 115 towards pins 104 said rods will advance through a blade on said pins to successively assemble blades on the rods, and each time after said plate and rodsrecede from blade receiving position the arm 105 will be rocked upwa-rdly to receive blades and downwardly to retain blades to be assembled on a pair of rods 115. The position of the parts shown in Figs. 1 and 8 represents a pair of rods loaded with a series of blades A and the adjacent pair of rods in position to receive blades. In such position of the parts the pairfof rods 115 having the blades assembled thereon may be removed from plate 117, and a pairof rods may. be replaced, during thetime that the pair of rods at the right hand side of Fig. 8 is receiving blades. When the last named pair of rods has received a supply of blades the handle 135 may be moved to the right, as in Fig. 11, to correspondingly adjust plate 117 so the last pair of rods will be moved away from blade receiving position and the other pair of rods will be moved into register with pins 104 on arm 105 to receive blades therefrom, and reversely so that each time that a pair of rods "has received a supply of blades the plate 117v will be shifted laterally for removing a pair of rods having blades and replacement of'rods.

The operation may be described as follows: I

The arm 113 causes pins 104 to pass through apertures or perforations in the blade A at blade receiving position, whereupon the arm 113 will recede and the arm 105 will be operated to carry the blade on pins 104 to the blade delivery and assembling position, and the appropriate pair of rods 115 will advance through the blade to assemble the latter on the rods, pushing the pins 104 back from the blade into the bores in arm 105. blade-receiving position to receive another blade on the pins 104. The blades are successivelyassembled on rods 115, and the blades assembled on rods 115 may be re- The arm 105 will return to out danger of injury.
